  • The present invention relates to a vibration damper, and preferably a marine vibration damper and a vibration damping structure. More particularly, it relates to a vibration damper and a vibration damping structure, having excellent vibration damping performance and fireproof performance.
    • Background Art
  • Conventionally, a method of overpainting a coating-type vibration damper such as an epoxy resin-based vibration damper on walls, floors and ceilings of engine rooms, resident rooms and the like has been employed to ensure vibration damping properties of ships. However, it is necessary to take drying time during overpainting. This required long working time, resulting in increase of working cost.
  • Furthermore, to ensure fireproof performance in addition to vibration damping performance in ships, there is the case that treatment for further imparting fireproof performance to the surface of a coating-type vibration damper is required. For example, Patent Document 1 proposes that a glass fiber fireproof layer and a metal film fireproof layer are provided on the outer surface of an epoxy vibration damper applied to a structure or equipment of a ship.
  • Furthermore, Patent Document 2 proposes a structure that a vibration damper comprising a viscoelastic material, and a steel plate are sandwiched between a floor steel plate and a deck composition layer, wherein the vibration damper and the steel plate, and the steel plate and the deck composition layer, are adhered through an adhesive layer.
